Application led April 26 To all whom t 'may concern.'

Be it known that l, Janne M. PriiNo'Us, a citizen of the United States, residingl at Pamplin, in the county of Appomattox and State of Virginia, have invented certain new and useful improvements in Switches, of which the following is a specification, reference being had to the accompanying drawings. Y

This invention relates to certain improvements in switches and it `is an object of the invention to provide a switch having novel and improved means whereby the same is rendered substantially noise-less upon the passing thereover of rolling stock whereby the life of the switch is materially prolonged.

lt is also an object of the invention to provide a novel and improved switch wherein parallel tongues are employed and mounted for rocking movement and coacting with a single frog, one of said tongues coacting with one side of a trackway and the second of said tonguescoacting with the opposite side of the trackway.

The invention, consists in the details of construction and in the combination and arrangement of the several parts of improved switch whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth. l

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure l is a view in top plan illustrating a switch mechanism constructed in accordance with an embodiment of my invention;

Fig. 2 is a fragmentary view partly in elevation and partly in transverse section illustrating certain details of my invention, said section being taken at a point intermediate the throw member and the frog and. looking in a direction tow'ard the throw member; and

Fig. 3 is a vation and partly in section taken on substantially the same line as Fig. 2, but looking in the opposite direction.

As disclosed in the accompanying draw- Specicaton of Letters Patent.

ings, T denotes a trackway having diverging therefrom the branch B, and F denotes a frog employed in connection with my improved switch and which is substantially li-shape in form having one longitudinal portion parallel with the outer side of the trackway T and its opposite marginal portion parallel with the outer side of the branch B.

P and P denote switch points pivotally mounted, as at l,.midway their length for rocking movement in a horizontal plane, theA opposite end portions of the point P being connected by the braces 2 pivotally engaged with the points P and P, whereby it will be perceived that said points P anc P will be in approximate parallelism irrespective of their rocking movement. .l As herein disclosed, the point P serves to maintain the trackway T closed while the point P serves to throw in the branch B.

iArs herein embodied, it is to be observed that the points P and P extend inwardly of the forward end or point of the frog F, but are provided with the recesses 3 wherebysaid points P and P, when in operative adjustment to the frog F, are in continuity therewith for a purpose which is believed to be clearly apparent tov those skilled in the art to whichmy invention appertains.

As herein disclosed, the braces Qhave their extremities arrangedwithin the openings 4 produced in the webs of the points P and P', and the brace remote from the frog F is eX- tended, as indicated at 5, and is disposed through the opening 7 produced in the outer rail of the trackway T and operatively engaged with the crank arm 8 carried by the shaft 9 disposed along one side of the trackway T.

The shaft 9 is provided with a second crank arm l0 operatively engaged with the throw member M movable in a direction substantially transverse to the trackway T and branch B and underlying the points P and P and disposed through an opening 11 produced in the outer rail of the trackway T. llt is to he understood that the connection between the extended portion 5 of the brace 2 and the crank 8 possesses suiiicient play to permit the requisite independent movement of the throw member M, to raise the points P and P before the rocking or swinging movement is imparted to said points.

v throwfmember M, the lower :wallof each of said recesses 12 constituting acam 14 'of predetermined pitch, the cam of one recess being reversely related to the cam of the l second recess, whereby it will beperceived that upon movement of the throw member M in one direction, one of the points P or P will be elevated, while the second of said points willbe permitted to drop. By this movement it will be perceived that either ofthe pointsmay be operativelyengaged with or disengaged from the locking lugs 15 which serve to hold a point in operative position relative to the frog F. It will also Yberreadily understood that the ends of the recesses 12 coact with the points P and P to impart the requisite rocking movement thereto.

The shaft 9 is provided with an upst-anding .lever 16 operated in a conventional manner by a. traimnan in order to properly adjust or throw the points P and P in accordance'with the necessities of practice. Y From `the foregoing description, it is thought to be obviousthat a switch constructed in accordance with myY invention is of an extremely simple and comparatively inexpensive nature and isparticularly well adapted foruse by reasony of the eonvenience and facility with 'which .it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood'as limiting myself to 'the precise arrangement and formation of the several parts herein shown in carrying out my invention -in practice. I claim.: Y y

1. A switch mechanism includinga frog,

iijqplil 91 this -pgtent may lbelohtaine'cl for pivotally moimted points coacting with the frog, means for causing the points to move in unison and 1n the same direction, and

locking lugs coacting With the points for holding said points in operative position, the throwing means for the points serving to elevate the points above the locking lugs so that said points may travel thereby.

2. A switch mechanism including a frog, points coacting with the frog and mounted for rocking movement, said points eoacting with the opposite sides of the frog, means for causing said points to move in unison and in the same general direction, and a throw member underlying the points and provided with recesses in which the points are seated.

3. A switch mechanism including a frog, points coacting with the frog and mounted for rocking movement, said points coacting with the Yopposite sides of the frog, means for causing said points to move in unison and in the same general direction, a throw member underlying the points and provided with recesses in which the points are seated, the bases of said recesses being provided with reversely related cams, and locking lugs coacting with the points, the cams of the recesses of the throw member serving to elevate the points above the locking lugs.

4. A switch including a frog, a point coacting therewith, locking lugs for holding the point in operative position relative to the frog, and a throw member for the point operable to move the point relative to the frog and vertically relative to the locking hws.

' n testimony whereof I hereunto aiiix my signature in the presence of two witnesses.
